Abstract Smoldering multiple myeloma (SMM) is an asymptomatic precursor state of (MM). Recently, MM was redefined to include biomarkers predicting a high risk progression from SMM, thus necessitating redefinition SMM and its stratification. We assembled large cohort patients meeting the revised IMWG criteria develop new stratification system. included 1996 patients, using stepwise selection multivariable analysis, we identified three independent factors at 2 years: serum M-protein >2 g/dL...
Headache and Pain Research publishes original articles, review short letters on all aspects of headache pain research. The main topics include migraine, cluster headache, tension-type intracranial hypotension, hypertension, reversible cerebral vasoconstriction syndrome, other primary or secondary disorders, related dizziness, psychological, cognitive problem. Research, the official journal Korean Society, aims to rapidly spread an updated advance in field readers patients, while fostering a...
Background Vestibular migraine (VM), the common term for recurrent vestibular symptoms with features, has been recognized in appendix criteria of third beta edition International Classification Headache Disorders (ICHD-3β). We applied VM a prospective, multicenter headache registry study. Methods Nine neurologists enrolled consecutive patients visiting outpatient clinics headache. The presenting disorder and additional diagnoses were classified according to ICHD-3β. rates diagnosed probable...
The present work addresses Au(III) extraction from chloride media using phosphonium-based ionic liquid (Cyphos IL 109) as a novel anion exchanger diluted in xylene. Gold(III) is extracted into the organic phase [P66614+][AuCl4– ] and can easily be stripped by reduction to Au(I) with CS(NH2)2/HCl or Na2S2O3. A series of extraction-stripping cycles show possible recirculation used solvent without loss performance, far gold(III) HCl/Cl– concerned. was quantitatively (99.4%) 0.1 mol L–1 HCl...
Objective To investigate suicidality related to cluster headache and factors associated with increased in patients. Methods In this multicenter study, 193 patients were recruited between September 2016 August 2018. Patients asked about their during attacks, specifically passive suicidal ideation, active suicide plan, attempt. Univariable multivariable logistic regression analyses performed evaluate the high ictal (sum of positive response ≥ 2). followed up when they between-bouts period....
Abstract Background In order to conserve resources without affecting the environment, an energy efficient leaching process has been studied recover platinum group metals ( PGMs ) from spent automotive catalyst using electro‐generated chlorine as a strong oxidant in separate reactor . Results The different parameters showed increase dissolution of (Pt, Pd, Rh) with HCl concentration, current density, time, and temperature but not pulp density. Leaching efficiencies 71% Pt, 68% Pd 60% Rh were...
Growth of multiple myeloma cells is controlled by various factors derived from host bone marrow microenvironments. Interaction between and stromal (BMSCs) plays an important role in the expression adhesive molecules secretion growth involved (MM) cell growth, survival, resistance to anticancer drugs. Recently, possibility developing novel anti‐cancer therapeutic strategies targeting both MM cell–BMSC interactions has been discussed. Here we present data showing that curcumin, a major...
The development of a hydrometallurgical process for the recycling waste Pb-free solder based on nitric acid leaching, followed by separation Ag and Cu through AgCl precipitation or cementation, was investigated. Nitric dissolved from material while converting tin to stannic oxide (SnO2), which is very sparingly soluble in HNO3 solution. More than 99% were 2 kmol·m−3 under leaching conditions 75°C, 100 kg·m−3 pulp density stirring at 400 rpm 120 min. addition NaCl powder used separate 125...
This research work focused on the simultaneous recovery of gold (40.5 mg/dm3) and iodine (748 from waste rinse water semiconductor industry using activated carbon. A batch study was conducted to optimize process parameters, such as contact time carbon dose, for water. The loading capacity adsorption found be 33.5 mg Au/g 835 I2/g carbon, respectively. Gold exist charcoal surface in two forms: ionic elemental gold. Aqua regia used convert metallic its form, small amount were removed by...
Background and Purpose— Ischemic stroke patients often have intracranial atherosclerosis (ICAS), despite heterogeneity in the cause of stroke. We tested hypothesis that ICAS burden can independently reflect risk long-term vascular outcome. Methods— This was a retrospective cohort study analyzing data from prospective registry enrolling consecutive with acute ischemic or transient attack. A total 1081 were categorized into no ICAS, single advanced (ICAS ≥2 different arteries) groups. Primary...
Introduction: This study assessed the therapeutic effectiveness of a single-pill combination (SPC) olmesartan/amlodipine plus rosuvastatin for blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) in patients with hypertension dyslipidemia. Methods: Adult dyslipidemia who were decided to be treated drug eligible. The primary endpoint was proportion achieved BP, LDL-C both BP treatment goals at weeks 24-48. Secondary endpoints 24-48 included changes levels from baseline;...
The pain lateralization in cluster headache (CH) may be related to the asymmetry functions of brain hemispheres. right-sided dominance CH has been found inconsistently across studies, and so we aimed characterize this identify factors influencing during current previous bouts. This study enrolled 227 patients from Korean Cluster Headache Registry between October 2018 December 2020. We evaluated side bouts, demographic features, clinical characteristics, including handedness. Multivariable...

This study deals with the reduction of tin oxide by hydrogen in temperature range 773∼1023 K and partial pressure 30.4∼101.3 kPa. It aims to investigate kinetics reaction between hydrogen. The is be related efforts extract metal decreasing emission carbon dioxide which causes global warming. experiments were carried out under isothermal condition atmosphere using TGA equipment. rate was found relatively fast whole conditions until ratio SnO2 approaches about 0.95. As an example, at 1023 a...
Comprehensive Application of the International Classification Headache Disorders Third Edition, Beta VersionThe purpose this study was to test feasibility and usefulness Disorders, third edition, beta version (ICHD-3β), compare differences with second edition (ICHD-2).Consecutive first-visit patients were recruited from 11 headache clinics in Korea.Headache classification performed accordance ICHD-3β.The characteristics headaches analyzed assessed by proportion unclassified disorders...
Cluster headaches (CH) are recurrent severe headaches, which impose a major burden on the life of patients. We investigated impact CH employment status and job burden.The study was sub-study Korean Headache Registry. Patients with were enrolled from September 2016 to February 2018 15 headache clinics in Korea. also control group age-sex matched patients migraine or tension-type headache. Moreover, including individuals without complaints recruited. All participants responded questionnaire...
Most processes for recovering zinc from electric arc furnace (EAF) dust employ carbon as a reducing agent oxide in the dust. In present work, reduction reaction of with presence various additives was kinetically studied. The effects temperature and Fe2O3, mill scale, CaCO3 on kinetics were measured range 1173–1373 K under nitrogen atmosphere. scale is one byproducts generated steel rolling process. It found experimental results that all three enhance rate carbon, but effect addition highest....
A novel process to simultaneously extract the precious metals such as gold, silver, platinum, palladium and rhodium from spent mobile phone printed circuit boards (PCBs) honeycomb-type auto catalysts by smelting using waste-copper slag without adding any collector or by-products dross, matte slime has been developed. In process, which is an industrial waste discharged copper smelter used not only a flux for controlling composition, but also metal capturing metals, plastic component contained...
